ߜ Processor: A 400 MHz Pentium II or better is best. The processor speed, expressed in MHz (megahertz) or GHz (gigahertz), is not that important as long as it’s over 400 MHz, but the faster the better. Linux can run on other Intel-compatible processors such as AMD, Cyrix, and VIA processors. ߜ RAM: RAM is the amount of memory your system has. As with process- ing speed, the more RAM, the better. You need 256MB to install both SUSE Linux and to comfortably run a GUI desktop. ߜ DVD/CD-ROM: You must have a DVD/CD-ROM drive and the PC must be able to boot from that drive. The exact model doesn’t matter. What mat- ters is how the DVD/CD-ROM drive connects to the PC. Most new PCs have DVD/CD-ROM drives that connect to the hard drive controller (called IDE for Integrated Drive Electronics or ATA for AT Attachment). If you add an external DVD/CD drive, it most likely connects to the USB port. Any IDE/ATA or USB DVD/CD-ROM works in SUSE Linux. ߜ Hard drives: Any IDE disk drive works in SUSE Linux. Another type of hard drive controller is SCSI (Small Computer System Interface), which SUSE Linux also supports. To comfortably install and play with SUSE Linux, you need about 5GB of hard drive space. ߜ Keyboard: All keyboards work with SUSE Linux and the X Window System. ߜ Mouse: The installation program can detect the mouse. All types of mice (such as PS/2 or USB) work with SUSE Linux and the X Window System. ߜ Video card: SUSE Linux works fine with all video cards (also known as display adapters) in text mode, but if you want the GUI desktop, you need a video card that works with the X Window System. The installer can detect a supported video card and configure the X Window System correctly. However, if the installer cannot detect the video card, it helps if you know the make and model of your video card. ߜ Monitor: The kind of monitor is not particularly critical except that it must be capable of displaying the screen resolutions that the video card uses. The screen resolution is expressed in terms of the number of picture elements (pixels), horizontally and vertically (for example, 1024 x 768). The installer can detect most modern monitors. If it does not detect your monitor, you can select a generic monitor type with a specific resolution such as 1024 x 768. You can also specify the monitor by its make and model (which you can find on the back of the monitor). ߜ Network interface card (NIC): Not all PCs have network interface cards, but if yours does, the installer can probably detect and use it. If you have problems, try to find the make and model (such as Linksys LNE100TX Fast Ethernet Adapter) so that you can search for information on whether SUSE Linux supports that card or not. ߜ SCSI controller: Some high-performance PCs have SCSI controllers that connect disk drives and other peripherals to a PC. If your PC happens to have a SCSI controller, you might want to find out the make and model of the controller. 25 Chapter 2: Installing SUSE Linux Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. ߜ Sound card: If your PC has a sound card and you want to have sound in SUSE Linux, you have to make sure it’s compatible. You can configure the sound card after successfully installing SUSE Linux. ߜ Modem: If you plan to dial out to the Internet, you need a modem that Linux supports. For software-based modems, called soft modems or win- modems, you may have to download a driver from the manufacturer (it may or may not be freely available). In addition to this hardware, you also need to find out the make and model of any printer you plan to use in SUSE Linux. To check if your PC’s hardware is compatible with SUSE Linux, visit the SUSE Linux Hardware Database at hardwaredb.suse.de. Installing SUSE Linux The companion DVD does not include the full SUSE Linux Professional distri- bution because it’s a commercial product. Instead, the DVD includes a Special Edition, which is similar to the personal edition that SUSE used to sell in ver- sions prior to 9.2. In this section, I describe the installation process for the companion DVD, but the steps are similar if you were to install SUSE Linux Professional. Booting your PC from the DVD/CD-ROM drive Most new PCs can boot directly from the DVD/CD-ROM drive, but some PCs may require intervention from you. Typically, the PC may be set to boot from the hard drive before the DVD/CD drive, and you have to get into SETUP to change the order of boot devices. To set up a PC to boot from the DVD drive, you have to go into SETUP as the PC powers up. The exact steps for entering SETUP and setting the boot device vary from one PC to the next, but typically they involve pressing a key such as F2. As the PC powers up, a brief message tells you what key to press to enter SETUP. When you’re in SETUP, you can designate the DVD/CD drive as the boot device. After your PC is set up to boot from the DVD/CD drive, simply put the DVD in the DVD/CD drive and restart your PC. Installing SUSE Linux from CDs or DVD To install SUSE Linux from CDs or a DVD, simply insert the first CD or the DVD into your PC’s CD/DVD drive and restart your PC (in Windows, choose 26 Part I: Getting to Know SUSE Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Start➪Shutdown and then select Restart from the dialog box). If you are using CDs, the installation steps are the same as that for the DVD except that you have to swap CDs when prompted by the installation program. After your PC powers up, a boot loader starts and displays an initial boot screen with a menu of items. Table 2-1 lists these boot menu items and their meaning. As you can see, you can perform a number of tasks from the boot screen, including booting an existing installation from the hard drive and starting a rescue system. Table 2-1 SUSE Installer Boot Menu Items Select This Item To Do This Boot from Hard Disk Boot the PC from a previously installed operating system from the hard drive. Installation Automatically detect hardware and then begin installing SUSE Linux. Installation — Disable support for ACPI (Advanced Configuration and ACPI Disabled Power Interface), but otherwise detect hardware and start SUSE installation. Installation — Disable potentially troublesome features such as ACPI, Safe Settings APM (Advanced Power Management), and DMA (direct memory access) for IDE interface and start installing SUSE. Select this option if the installation hangs with any of the other options. Manual Installation Control all aspects of installation, including loading device driver modules for your PC’s hardware. Rescue System Start a small Linux system in memory so that you can trou- bleshoot by logging in as root. Memory Test Check to see if the PC’s memory has any problems. Along the bottom of the SUSE installer boot screen, you see some information about using the function keys F1 through F6. Table 2-2 explains what each of these functions does. You can also provide other installer options — as well as Linux kernel options — at the Boot Options text box below the boot menu. The in- staller options control some aspects of the installer’s behavior, whereas the kernel options are passed to the Linux kernel that starts when you start the installation. Typically you don’t have to provide any of these options to install SUSE Linux. 27 Chapter 2: Installing SUSE Linux Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Table 2-2 Using Function Keys at the SUSE Installer Boot Screen Press This To Do This Function Key F1 Get context-sensitive help — help information that depends on the currently selected item. Use the up- and down-arrow keys to read the Help screen and the left- and right-arrow keys to jump between topics. You can dismiss the Help screen by pressing Escape. F2 Select a screen resolution that you want the YaST installer to use for its GUI. If the GUI screen fails to appear, you can select Text Mode for a text mode interface. F3 Select the source from where you want to install. The choices are CD or DVD, network sources with different protocols such as FTP, HTTP, NFS, and SLP (Service Location Protocol). Typically you can leave this at its default choice of CD or DVD. F4 Select the language and keyboard mapping to be used by the boot loader. F5 View kernel messages as the Linux kernel loads. This could help you identify problems if the installation hangs. F6 Update a driver module for new hardware for which drivers may not be on the CD or DVD. You will be prompted to insert the updated driver module on a floppy or CD-ROM after you start the installation. The installer initially picks a rather high screen resolution for the GUI screen (typically, 1280 x 1024 pixels). To change the resolution, press F2, which brings up a menu from which you can select other screen resolutions, such as 1024 x 768 pixels. After setting the screen resolution by pressing F2, select Installation from the boot menu and press Enter. This loads the Linux kernel from the DVD or CD. The Linux kernel starts running the YaST installation program. For the rest of the installation, you work with YaST’s GUI screens. Starting the SUSE install in YaST YaST — the SUSE installer — displays a GUI screen (see Figure 2-1) from which you install SUSE Linux on your PC’s hard drive and configure it.The left-hand side of the YaST screen shows the list of installation steps, organized into two broad categories of tasks — Base Installation and Configuration. An arrow marks the current step. For example, in Figure 2-1, the arrow marks the language selection step. After the step is complete, YaST displays a check mark next to the step. 28 Part I: Getting to Know SUSE Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. On the right-hand side of the YaST screen (see Figure 2-1), you see the options for the current step. You have to select options and then click Accept to pro- ceed to the next installation step. You can abort the installation at any time by pressing the Abort key, up until you confirm that you want to really proceed with the installation. At any installation step, click the life buoy button at the lower-left corner of the YaST screen (refer to Figure 2-1) to view context-sensitive help informa- tion for the current step. The help appears on the left-hand side of the YaST screen. Press the button again to return to view the list of installation steps. Follow these steps to complete the initial installation steps in the YaST installer: 1. Select the language to be used during installation and for use in the installed SUSE Linux system. Then click Accept. YaST probes the hardware and loads driver modules. YaST may prompt you to confirm that it should load some driver modules. Then YaST dis- plays a dialog box (shown in Figure 2-2) that prompts you for the next step. 2. Assuming that you are installing SUSE for the first time, select New Installation and click OK. YaST gathers information about the system and prepares a list of all the installation settings, organized by category, and displays it in the Installation Settings screen (see Figure 2-3). Table 2-3 summarizes the installation settings categories. Remember to scroll down to see all the installation settings in the screen shown in Figure 2-3. Figure 2-1: The YaST installer’s main GUI screen. 29 Chapter 2: Installing SUSE Linux Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Table 2-3 Installation Settings Categories Category What These Settings Specify System Information about the PC’s hardware, including the processor type, amount of memory, hard drive, keyboard, mouse, graphics card, sound, and Ethernet card. Mode Whether this is a new installation or an update. Keyboard Layout Language and layout of the keyboard. Mouse Type of mouse (for example, PS/2 mouse). Partitioning Information about the hard drive partitions that will be for- matted and any partitions that would be mounted on the Linux file system. You can edit this category and select the hard drive with Microsoft Windows. Then YaST offers to either delete or shrink the Windows partition. You can shrink the Windows partition and install SUSE Linux in the newly created space on the hard drive. Software What software YaST will install. The default is a typical system with KDE desktop and office applications. If you want, you can select a GNOME desktop by editing this category. Booting Information about the boot loader that takes care of start- ing Linux (as well as other operating systems, such as Windows XP, that may be on the hard drive) when you reboot the PC. The default is the GRUB boot loader, installed on the hard drive’s master boot record (MBR). Time Zone Current time zone and how the hardware clock stores time. The default is the USA/Pacific time zone, which you may need to change. Figure 2-2: Select New Installation and click OK. 30 Part I: Getting to Know SUSE Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Category What These Settings Specify Language The language to be used by the installed SUSE Linux system. Default Runlevel What processes Linux starts after booting. The default runlevel is 5, which gives you a full multiuser system with networks enabled and a graphical login screen. 3. Scroll down the list of installation settings and click a heading to view the settings and make any changes. If you are installing on a PC that had only Windows installed, the Partitioning settings would suggest shrinking the Windows partition and creating space for SUSE Linux. If you want to change the size of the SUSE Linux partition, click Partitioning, and then click Next in the next screen. YaST then asks you whether you want to delete the Windows partition or shrink it (see Figure 2-4). Select Shrink Windows Partition and click Next. YaST then displays a window (Figure 2-5) where you can specify the size of the Windows and SUSE Linux partitions by clicking and dragging the slider. Figure 2-3: Click a heading to make changes to that category of settings. 31 Chapter 2: Installing SUSE Linux Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. After indicating the size of the Windows partition (which automatically allocates the rest of the hard drive to SUSE Linux), click Next. Note that nothing happens to the hard drive partitions until you confirm that you really want YaST to proceed with the SUSE Linux installation. If you want to change the desktop from the default KDE to GNOME, click Software in the main YaST Installation Settings screen (see Figure 2-3). YaST displays a new screen where you can select Standard System with GNOME and click Accept (see Figure 2-6). You can accept the rest of the settings as is, but you probably need to change the time zone. To change the time zone, click the Time Zone sec- tion heading from the Installation Settings screen (Figure 2-3). From the next screen (see Figure 2-7), select the correct time zone and click Accept to return to the Installation Settings screen. 4. After you have checked all installation settings, click Accept. YaST displays a warning dialog box (shown in Figure 2-8) that tells you that this is the point of no return and you can commit to the installation by clicking Install or return to the installation settings by clicking Back. Figure 2-4: Select Shrink Windows Partition and click Next. 32 Part I: Getting to Know SUSE Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.

If you are certain that you want to continue with the installation, click the Install button. YaST then begins the installation, which includes formatting and prepar- ing the hard drive partitions and copying SUSE Linux files to the hard drive. As YaST installs the software packages, it displays a slide show that intro- duces various features of SUSE Linux. After the base installation is complete, YaST installs the boot loader and reboots the system. Figure 2-8: Click the Install button only if you are sure.
